SUSPENSION-RAILWAY.

Specification of Letters Patent.

To all *whom it may concern Be it known that I, JOSIAH H. SMITH, a citizen of the United States, residing at Philadelphia; in the county of Philadelphia have invented certain new and useful Improvements in Suspension-Railways, of which the following is a specification. 7

My invention relates to improvements in suspension railways, the object of the invention being to provide a suspension railway which is especially adapted for use in subways. I

A further object is to provide an improved construction of track supporting girders having an improved connection with transverse girders, the latter and the connecting means being anchored in cement forming the top of the subway and the foundation of the base of the street above, so that the parts are rigidly secured together andgheld against movement in any direction. 1

With these and other objectsin view, the invention consists in certain novel features of construction and combinations and arof parts as will be more, fully hereinafter described and pointed out inthe claims. V

In the accompanying drawings: Figure 1 is a view in longitudinal section illustrating my improvements. Fig. 2 is a view in transverse section on the line 2-2 of Fig. 1, a portion of the subway roof construction being broken away. 'Fig. 3 is an enlarged view in section on the line 3-3 of Fig. 2, and Fig. 1 is a view in vertical section on the line 1- 1 of Fig. .2.

1 represents an underground tunnel or subway having side walls 2, a bottom wall 3, and a-top wall 1. The top wall 4 constitutes the supporting base of the street 5 above, and is ordinarily of cement. In this cement roof 1, transverse girders 6 are embedded. These girders 6 are ordinarily extremely heavy I-beams, and act as supports for the wall 1, the cement being arched between the I-beams as shown at 7 8 represents my improved longitudinal girders which are composed of upper an lower angle bars 9 and IO'respectively secured together by-cross diagonal struts .11

and vertical struts 15.

- and scope of At the points of intersection with the transverse I-beams 6, the longitudinal girders 8 are connected by anchor plates 12. These anchor plates 12 extend between the angle bars 9 and 10, and are riveted thereto. Above the bars 9, the plates 12 are recessed as shown at 13 to accommodate the base flanges of the I-beams 6, and said plates at their upper ends incline toward the I-beams, and at their opposite edges are provided with angle bars 1 1. The angle bars 1 1, and the portion of the plates adjacent the I- beams 6, are embedded in the cement of wall 4:, so that the plates are securely anchored in the wall. Furthermore, the walls of, recesses 13 provide supports upon the lower base flanges of the I-beams 6, hence the longitudinal girders are supported rigidly on the I-beams and require no additional support for suspending the cars in the subway. I

In constructing new subways, the parts will all be assembled before the cement wall A is set. I In utilizing my improvements in subways already constructed, it is necessary to cut out the cement wall suliiciently for the accommodation of the plates 12 with their angle bar edges, and after the parts are connected, thev cement is filled in, so that the parts become securely anchored. The crossed diagonal struts 11 are secured at their ends to the plates 12, and the vertical struts 15 support laterally projecting cantalivers 16 to which I-beams 17 are connected and support rails 18.

19'represents the cars of a subway train suspended from brackets 20 having wheels 21 to run on the tracks 22 supported on I- beams 17.

Various slight changes might be made in the general form and arrangement of parts describedv without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit the appended claims.

described my invention, what Having thus Let- I claim as new and desire to secure by ters Patent is:

2. The combination with a series of transverse beams embedded in cement, of a longitudinal girder located below and extending at right angles to the transverse'beams, anchor plates secured to and the girder, said anchor plates projecting above the girder embedded in the cement, and secured to opposite sides of the beams, said anchor plates having angles at their edges embedded in the cement, substantially as described.

3. The combination with a series of transverse beams embedded in cement, of a longitudinal girder located below and extending at right angles to the transverse beams, anchor plates secured to and forming parts of the girder, said anchor plates projecting above the girder embedded in the cement, and secured to opposite sides of the beams, and said anchor plates recessed at their edges conforming in shape to the-shape of the beams, substantially as described.

4. The combination with a series of transverse beams embedded in cement, of a longitudinal girder located below and extending at right angles to the transverse beams, anchor plates secured to and forming parts of the girder, said anchor plates projecting above the girder embedded'in the cement, and secured to opposite sides or" the beams, said anchor plates having angles at their edges embedded in the cement, and said anchor plates recessed at their edges conforming in shape to the shape of the beams, substantially as described.

5. In a subway, the combination with a roof construction consisting of transverse I-beams embedded'in cement, of a longitudinal girder consisting of upper and lower parallel angle bars, anchor plates secured between both pairs of angle bars and projecting above the girder, said plates having recesses in their edges receiving the base flange of the I-beams, substantially as described.
